PORTABLE ELECTRIC-LIGHT FIXTURE. 7

I Specification of Letters Patent. I Patented May 28,1912. Applicationfiled October 13, 1910. Serial No. 586,887.

To all whom it may concern:

Be it known that I, LEROY A. WILLIAM- SUN, of Boston, county of Suffolk,and State of Massachusetts, have invented certain new and usefulImprovements in Portable Electric-Light Fixtures; and I do herebydeclare the following specification, taken in connection with theaccompanying drawin s, forming a part of the same, to be a full, 0 car,and exact description thereof.

My inventlon relates to an improved form of portable electric lightfixture of the same general character as the fixture forming the subjectof my Letters Patent, No. 914,772, dated March 9, 1909. p I

It is the object of-the present invention to provide a form of portableelectric light fixture which is extremely simple in construction andcheap to manufacture. a

To that end, the invention consists in the novel construction,arrangement and combination of parts hereina er described and claimed,reference being made to the accompanying drawings, in which- Figure 1 isa side elevation of my improved form of portable fixture showing thesame in use. Fig. 2 is a similar view showing the fixture out of use andwith one side verse sectional view through the center of Referring tothe drawings, A represents the casing and B an attaching plug which ispreferably made as a part of the casing. J ournaled in the walls of thecasing A. is a hollow hub a, in which is a spring b..' The outer end ofthe spring I) is fastened to theis fastened to a stud d which passesthrong the-hub a and is secured at eachend to t e walls of the casing.In the hub a is a transverse partition e which is provided upon one sidewith ratchet teeth 1 which are arranged and adapted to engage the teethupona ratchet-wheel g WhlCh is splined u on the stud d. The stud disprovided wit a longitudinal slot h and surrounding said stud a coiledsprin i,'one end of which bears against the rate et-wheel g and theother end of which bearsagainst one ofthe walls of the casing A. Mountedto-slide longitudinall'y in the stud d is a in l, the inner end of whichis connected to t e ratchet-wheel g. On one end of the hub a are twometal rings a which are in frictional enga ement with two metal rings aon the e of one of the wallsof' the casing A, The metal rings a areconnected bya quantity of lamp cord 9'" wound on'the hub a to a lampsocket is, a

and the metal rings a are connected by wlres j to the plug B.

The operation of the device is as follows:

Remove the lamp from the stationary fixture and insert plug B into saidfixture. Then draw lamp socket 7: out of casing A and insert the lamptaken'from the stationary fixture therein. Then draw as much of the cordy out of the casing as is desired. 'As

the cord is drawn from the casing the hub a will revolve and therebywind up the spring b and when the desired amount of cord has beenwithdrawn the hub will be held against movement from the action of thespring by the ratchet wheel 9. When now the user has ceased using thedevice he simply pushes in the pm Z, thereby throwing the ratchetwheelout of engagement with the ratchetteeth f and the hub' a will berevolved by the spring I) in a direction to wind up'the cord and drawthe socket is into the casing.

As soon as the socket is is partly or wholly within the casing,pressureis removed from the pin Z and the spring 71 will force the ratchet-wheel9 back into contact with the ratchet-teeth f and the hub a will thus belocked against further revolution in a direction to wind up the cord.

What I claim as my invention and desire'to secure by Letters Patent is:e

1. In a device of the character described, the combination, with asuitable casing, of an attaching plug upon the exterior thereof, a hubmountedto revolve upon the interior of said casing, a quantity ofelectric lamp cord wound on said hub, a lamp socket attached to one endof said cord,means connecting the other end of said cord to theattaching plug, spring-actuated means for relamp socket on one end ofsaid cord, and means connecting the other end of said cord to theattaching plug.

8. In a device of the character described, the combination, with acasing, of an attaching plug upon the exterior thereof, a hollow hubmounted to revolve within said casing; a spring arranged to revolve saidhub, a transverse dpartition upon the interior of said hub provi ed witha series of ratchetteeth, a stationary stud extending through said hub,a ratchet-wheel mounted to slide on said stud and normally held in engaement with said ratchet-teeth by means 0% a spring surrounding said studbetween said ratchet-wheel and the casing, a pin slidably cord havingone end mounted in said stud and having its inner end connected to saidratchet-wheel, two metal rings upon the exterior of said hub arranged tocontact with two metal rings upon the interior of the casing, wiresconmeeting the metal rings upon the casing with the attaching plug, andan electric light connected to the metal rings upon the hub and theother end connected to a lamp socket, said cord being arranged andadapted to be wound upon the revolving hub.
